I have several annotations on my map view and I have a detail view that opens when you tap the button on the annotation. The detail view has a label for the title from the annotation and a label for the subtitle form the annotation. I'm trying to have the title and subtitle labels show the corresponding text from the annotation that gets selected. There are two problems I'm having with it. One, the labels aren't even showing up. Two, I inserted an NSLog to make sure the correct text gets sent to the label but no matter which annotation is selected, the title and subtitle are always from the last annotation added.
Here is some code:
AnnotationDetailView.h
AnnotationDetailView.m
